FIELD OF THE TECHNOLOGY

The present technology relates to portable devices, such as cell phones,and more particularly relates to use of television in conjunction withsuch devices.

BACKGROUND AND SUMMARY

The convergence of television and the internet continues. Recentlyintroduced televisions (as well as various set-top boxes and Blu-Rayplayers) enable viewers to interact with “TV Widgets.”

As Yahoo explained in an introductory press release in August, 2008, theWidget Channel is a television application framework that allowsconsumers to enjoy rich Internet applications designed for the TV whilewatching their favorite TV programs. The technology includes the Yahoo!Widget Engine—an applications platform that enables TV watchers tointeract with and enjoy a rich set of “TV Widgets,” or small Internetapplications designed to complement and enhance the traditional TVwatching experience and bring content, information and communityfeatures available on the Internet within easy reach of the remotecontrol. The Widget Channel also allows developers to use Javascript®,XML, HTML and Adobe Flash® technology to write TV applications for theplatform, extending the power and compatibility of PC applicationdeveloper programs to TV and related consumer electronic devices.

Also supporting the initiative are Intel (whose Media Processor CE 3100is used in initial implementations of the technology) and numerouspartners who have authored widgets, including eBay, MySpace, CBS, APNews, The New York Times, Netflix, Amazon, Blockbuster, CinemaNow,Showtime, USA TODAY, Pandora, Rhapsody, Twitter, CBS Sports FantasyFootball, Acdeo Funspot Games, and Flickr. Yahoo is also making itsnews, weather, video and finance web offerings available in widget form.Manufacturers that are supporting the Widget Channel applicationsframework in their television offerings include Samsung, Sony, LG,Toshiba and Vizio.

Intel and Yahoo provide a Widget Development Kit (WDK) to interesteddevelopers, CE manufactures, advertisers, and content publishers.Comcast has also developed TV Widgets for tru2way capable HDTVs in orderto create a richer set-top-less environment. (Tru2way is a Java-basedplatform with open API specifications, built into various televisions,settop boxes, DVRs, etc., to enable interactive cable services such aselectronic program guides, advertisements, games, chat, web browsing,etc.)

The widget functionality is launched by pressing a special button on thetelevision's remote control, which brings up the TV Widget dock—anoverlay bar presented along the bottom of the television screen,populated with user-selected widgets (FIG. 5). The user operates arrowkeys on the remote control to navigate to a desired application, andthen presses an Enter button on the remote to invoke the chosen widget.

When a widget is invoked, it typically opens up as a sidebar window onthe screen. For example, the Flickr widget presents different photoalbums, from which the user can select pictures to view (FIG. 6). Aslideshow—consuming the entire television screen—can be launched, ifdesired.

The Blockbuster widget, when launched, streams a high-definition trailerfor a movie. The AP News widget presents a crawling display at thebottom of the screen with news headlines from desired categories (local,international, business, etc.). The CinemaNow widget allows a user tonavigate through indexes of movies to select a desired movie foron-demand web viewing on the television screen. The MySpace widgetallows user to read messages, view photos, etc., in a screen-sidedisplay. The Ebay widget permits shopping, and monitoring of the user'sauctions, etc.

The technology is being marketed, in part, as a way to permit internetbrowsing from the family television—without having a computer in theuser's lap. As a Sony representative explained at CES 2009, “At home, mywife likes to surf the internet or watch weather, news and sports withher laptop while she's watching TV. Now she'll be able to accomplishthose functions on the television set itself.” Continuing, therepresentative explained, “For customers who really like sports, andyou're watching your favorite sports game and you have your computergoing to follow other games, or you're doing it on a Blackberry-typedevice, now you'll be able to accomplish all of that in a very easy,user friendly fashion just on the screen of your Sony Bravia TV.”

Contrary to these stated views, applicant believes that use of a secondscreen while watching television offers advantages to users, rather thanbeing a problem that should be eliminated. (Instead, applicant believesexcessive use of a shared screen is the underlying problem that hasdoomed interactive TV experiences. Indeed, who blocked out the catcherin the baseball game of FIG. 6 to review family photos on Flickr?)

In accordance with one aspect of the technology, TV widgets can betransferred to a cell phone, where they can be enjoyed by a user withoutconsuming space on the television screen, and distracting other viewers.

In accordance with another aspect, a widget running on the user's cellphone provides a richer experience than the widget running on thetelevision screen. (Since others may be watching the television screen,widget software typically tries to economize use of the televisionscreen space. Functionality is thereby impaired. The widget running onthe user's small screen does not have the constraint of consideringother viewers.)

In accordance with another aspect of the technology, a network-connectedtelevision uses network protocols to advertise widgets to other deviceson the network (e.g., cell phones), which can then download same.

In accordance with still another aspect, a cell phone's text-entry userinterface is invoked to input text to a widget running on a television.

In accordance with yet another aspect of the technology, a TV widget maybe transferred to a cell phone through interaction with a non-networkconnected television.

The foregoing are just a few of the novel aspects of the presenttechnology. These and other features and advantages will be more readilyapparent from the following detailed description, which proceeds withreference to the accompanying drawings.

DETAILED DESCRIPTION

Referring to FIG. 1, an illustrative implementation 10 using aspects ofthe present technology may include a television 11, a cell phone 12, arouter 14, and one or more internet-connected servers 13.

While television 11 is shown as a stand-alone unit, this term includessystems of various descriptions. For example, a “television” may includeone or more of a monitor, a TV receiver, a set-top box, a digital videorecorder, a Blu-Ray disc player, etc.

The depicted router 14 is connected to the internet 15, e.g., through acable or DSL modem, and defines a home network 16—with both wired (e.g.,Ethernet) and wireless (e.g., WiFi, 802.11) connections. The wiredconnection connects to a network connection 17 on the television 11, andmay also connect to other devices (e.g., desktop computer 18). Thewireless connection extends to other devices in the home domain, such ascell phone 12 and a laptop computer 20.

The television 11 also has an input 22 that is connected to a source ofvideo programming. This source may include a set-top box, a satellitereceiver, a cable network, or even an antenna. In some usage models thevideo programming may be provided across the network connection 17,rather than through a separate input.

Referring to FIG. 2, one aspect of the present technology is anarrangement for easily downloading a widget to a cell phone.

The Apple iPhone is renowned for its ease of use, and the Apple iPhoneApp Store is similarly esteemed. To download a new application, the usernavigates to the App Store web page, and navigates within the store to adesired application (e.g., by browsing, by text entry, by picking fromTop Apps lists, etc). A payment is made—if required—and the user theninstructs the application to be downloaded from the store to the phone.The downloaded application appears as an icon on the user's iPhonescreen.

Although the App Store download arrangement is regarded as a model ofstraightforward simplicity, the present technology is simpler. When awidget is shown on the television screen, the user simply manipulatesthe cell phone to express interest. A gesture or two later, the widgetis on the cell phone.

Consider the widgets shown along the base of the television screen 30 inFIG. 5. Shown are a Flickr widget 32, a weather widget, a stock ticketwidget, and a videos-on-demand widget.

The user may express interest by pressing a virtual button on the iPhone(e.g., a GetWidget application). Or the iPhone may have a WatchingTVsuite of software programs that automatically launches and runs in thebackground whenever the iPhone detects a nearby television (or it may bemanually invoked by the user). While this suite of software is running,a simple shake of the iPhone, or a gesture in the direction of thescreen, may signify the user's interest. A great number of other ways ofsensing user interest are possible.

When there are several widgets displayed on the television (as in FIG.5), and the user expresses interest, icons corresponding to all of thewidgets are transferred to the iPhone. These icons wiggle on the iPhonedisplay, inviting the user to press one to identify which is desired. Inresponse to the user selection, the full software code for the selectedwidget is downloaded to the iPhone. The selected icon stabilizes, andthe unselected icons disappear.

(If only one widget is on the television screen when the user expressesinterest, there is no need for selection. The corresponding software isimmediately downloaded to the iPhone, and the icon appears on the iPhonescreen.)

As detailed below, the behind-the-scenes interactions that enable thissimple downloading are a bit more complex, but from the user'sstandpoint it is an intuitive, easy process.

In the arrangements contemplated by Yahoo and its partners, a televisioncomes with a small selection of pre-loaded widgets. To obtain otherwidgets, the user navigates to the Yahoo Widgets page on the web anddownloads additional widgets from a large catalog of offerings.

Applicant believes other usage models will emerge and gain prominence.

In one such foreseen usage model, widgets are associated with differenttelevision programming. There may be a NBC Sports Superbowl widget, aCBS News widget, a Seattle Seahawks widget, an ESPN Monday NightFootball widget, a WRKG weather widget, a Cox Cable widget, etc.

Each such widget is branded, and provides a look (and optionally a“feel”) congruent with that of the programming or programmer with whichit is associated. (Look and feel signifies the experience a user haswith a product—such as a television show. Look can encompass aspects ofdesign, such as colors, shapes, layout and typefaces. Feel can encompassthe behavior of dynamic elements such as buttons, boxes, menus,transitions, sound effects, and other interactivity.)

In the contemplated usage model, when a user changes channels on a TV,the TV checks for widgets relevant to that channel and time (andoptionally location), and alerts to the user to same. If the user tunesto Monday Night Football on ESPN, a logo may appear on the screenadvising the user of the availability of the ESPN Monday Night Footballwidget. This logo may fade out after a few moments, but can be recalledby operating a Widget button on the television remote (in which case itis presented among the other available widgets along the bottom bar), ora similar button in the Watching TV suite of iPhone software. If theuser expresses interest in the offered widget (e.g., by using thetelevision remote control to highlight the widget, and pressing Enter,or by the arrangement earlier described for selecting widgets fordownload to a cell phone), the widget can be downloaded and run.

Thus, in this model, relevant widgets are “pushed” to the TV screen forpossible selection, rather than being “pulled” by the user, e.g., fromthe Yahoo Widgets page.

In accordance with another aspect of the present technology, widgets mayprovide a richer set of functionality when run on a cell phone, thanwhen run on the television. (On the television, screen obstruction is anissue: there may be other viewers who do not share the user's interestin a particular widget. Note how the baseball catcher on the left sideof the screen is hidden in FIG. 6, after the Flickr widget is invoked).

Consider an ESPN Monday Night Football widget. When selected on thetelevision screen, it may pop up a side-screen window on which gamestatistics, or game scores, are presented in scrolling fashion. Toreduce interference with viewing of the football game, the spaceavailable to the widget is limited.

When the widget is invoked on the cell phone screen, in contrast, spaceis not a constraint. The widget can occupy the full screen, yet none ofthe action on the television screen is concealed. So instead ofspace-constrained output, the ESPN Monday Night Football widget canoffer a variety of other options—commonly involving the full screen.Instead of just listing scores of other games, the scores may behyperlinked—allowing the user to select a score (e.g., by touchscreen)and link to a full-cell-screen, live video feed from that other game.

Similarly, it will be recognized that ESPN's television crew has cameraspositioned around the stadium, focused on different subjects. The ESPNproducer—typically in a television truck in the parking lot—switchesbetween the different camera feeds to produce the familiar networkfootball footage. But some viewers have special interests that may beserved by watching feeds not selected by the producer. A viewer who is areceiver on his high school football team may want to watch a feed froma camera covering a favorite pass receiver. A viewer who is himself afootball coach may be interested in watching one of the coaches. Suchalternate camera views may be among the options that the widget mayoffer to viewers on the cell phone, which are not available to viewerson the television screen.

Still other options may include player interviews, trivia games, etc.

Games are a further example of the richer functionality available on thecell phone platform. Widgets run on television screens are weak on textinput. A TV remote allows a user to navigate up, down, left and rightamong displayed buttons, but provides only clumsy text input—if any. Incontrast, text-entry on cell phones is common, and despite spaceconstraints, many users are proficient. Inputs include physical keys(Blackberry), virtual keyboards (iPhone), and stylus text entry (e.g.,Palm Graffiti, MobileWrite, etc.).

In one arrangement, the same binary software code is used by both thetelevision and the cell phone. When executing, the code checks whichplatform is executing it, and varies its behavior accordingly. In otherarrangements, variant widgets are used—one tailored to the television,and one tailored to the cell phone.

In some embodiments, hybrid execution environments are employed. Forexample, text entry may be done on the cell phone, and visual output maybe presented on the television screen.

Exemplary Implementation

Delving further into technical implementations and features, the cellphone and the television are basically computers, equipped with slightlydifferent components. As shown in FIGS. 3 and 4, each includes aprocessor, memory, and display. The processor in the cell phone is aSamsung S5L8900 ARM 620 MHz CPU, whereas the Intel Media Processor CE3100 (based on the familiar X86 architecture) is used in the television.The memory in the cell phone comprises 128 MB of static DRAM, togetherwith 8 or 16 GB of flash memory. A similar configuration may be used inthe television, or additional memory can be provided to accommodateadvanced video requirements. A disc storage can be provided instead or,or in addition to, flash memory.

Both devices store software in their memory, including an operatingsystem, application programs (including widget software), and userinterface software. (For details on the multi-touch interface employedby the iPhone, see Apple's U.S. Pat. No. 7,479,949.)

While the user interfaces for both devices are highly reliant onsoftware, each has some physical UI components as well, such as thephysical touch screen on the iPhone, and buttons on the television andits remote control

The display on the cell phone is obviously smaller than on thetelevision. The cell phone display can be a 3.5″ (diagonally) LCD, with480×320 pixels. The television display can be an LCD, OLED or plasmadisplay, measuring 20 inches or more (diagonally), with a resolution of,e.g., 1920×1080 pixels.

Both devices include a network adapter. The cell phone is equipped witha WiFi adapter. Additionally, it can communicate using Quad bandGSM/GPRS/EDGE: GSM 850/900/1800/1900. The television has an Ethernet(IEEE 802.3) interface.

Unlike the television, the cell phone additionally includes a camera(e.g., a 2 megapixel image sensor with associated lens, A/D converter,etc.) and a microphone. It also has a module by which it can determineits location. This module commonly performs location finding byreference to cell towers and WiFi networks. However, in otherembodiments a GPS receiver can be included.

Although televisions do not yet have location-finding capability,applicant believes future generations of televisions should be providedwith such functionality. In addition to other advantages, this willpermit a television to determine its position relative to other devices,and vice-versa. One way in which this would be useful would be forauto-launching a WatchingTV suite of software applications on a nearbycell phone, when in proximity to a nearby, operating television.

One emerging location-finding technology relies on radio signaling ofthe sort that that commonly occurs between devices (e.g., WiFi,cellular, broadcast television). Given enough devices, the signalsthemselves—and the imperfect digital clock signals that controlthem—form a reference system from which both highly accurate time andposition can be abstracted. Such technology is detailed in laid-openinternational patent publication WO08/073347.

In one particular implementation of the FIG. 2 system, the televisionadvertises the widgets that are available for downloading to the cellphone 12 (or to other devices on the home network, such as laptop 20, orcomputer 18). This can be done using the Bonjour protocol.

Bonjour is Apple's trade name for its implementation of Zeroconf—aservice discovery protocol. Bonjour locates devices on the localnetwork, and identifies the services that each offers, using multicastDomain Name System service records. This software is built into theApple MAC OS X operating system, and is also included in the Apple“Remote” application for the iPhone, where it is used to establishconnections to iTunes libraries via WiFi. (TiVo uses Bonjour to locatedigital video recorders and shared media libraries.)

Bonjour services are implemented at the application level largely usingstandard TCP/IP calls, rather than in the operating system. Apple hasmade the source code of the Bonjour multicast DNS responder—the corecomponent of service discovery—available as a Darwin open sourceproject. The project provides source code to build the responder daemonfor a wide range of platforms, including Mac OS X, Linux, *BSD, Solaris,and Windows. In addition, Apple provides a user-installable set ofservices called Bonjour for Windows, as well as Java libraries.

In a sample implementation of the present technology, the televisionprocessor uses Bonjour to periodically (e.g., every second or everyseveral seconds) send out on the home network subnet one or more packetsadvertising widgets that are available for downloading. The packetsdetail the names of the available widgets, and also provide the IPaddress of the television or other network location from which they areavailable. Desirably the widgets are listed in the order of their latestappearance on the television screen, so that the most-recently-presentedwidgets can be identified by listening devices. (The broadcast may belimited to just the widgets presently shown on the television screen, ora more exhaustive listing can be provided.)

All devices on the home network, including the WiFi-connected cell phone12, can monitor these advertisements. The cell phone can cache themost-recently-received packet data, detailing the widgets currentlyavailable.

If the user manipulates the cell phone to express an interest in awidget, the cell phone listens for the Bonjour broadcast from thetelevision (if it has not already been listening and caching suchinformation). It then establishes a secure socket connection with thetelevision—using the IP address from Bonjour broadcast. In oneparticular implementation, the cell phone requests transfer of softwarefor the widget most-recently-presented on the television screen. Inanother implementation, the cell phone requests transfer of icons forall of the widgets then-shown in the bar along the bottom of thetelevision screen (or for the N most-recently-presented widgets). Theseicons are displayed to the user on the cell phone screen, in vibratingfashion. Software on the cell phone enables the user to select one ofthe vibrating icons, causing its vibration to stop. The cell phone thenrequests, over the SSL connection, download of the software for thatwidget from the television. When download completes, the cell phonesoftware removes the non-selected icons from the display—leaving theicon for the widget for which software was transferred.

During transfer of the widget software, the cell phone (or television)can emit a sound effect, such as a whooshing or sucking sound, toconfirm to the user that a transfer is underway.

In some embodiments, the default behavior is for the cell phone toautomatically launch the widget when the transfer is complete, so nofurther action by the user is required.

There are many variants and derivatives of Bonjour that can be employedin different embodiments. For example, the Bonjour Browser is a CreativeCommons-licensed application that displays all services declared usingBonjour. Similarly, JBonjourBrowser is a Java-based version of thisfunctionality, open-source and available under the GNU General PublicLicense.

In other implementations a secure FTP connection can be establishedbetween the cell phone and the television to transfer the widget iconand/or binary software, e.g., in a compressed .zip file.

In still other implementations, Microsoft's .NET framework can be used.Using the remote services of .NET, a virtual machine running on the cellphone can ask what other portable execution components exist on otherends of the connection. .NET can open up a .NET connection to a remotemachine (e.g., the television), and inquire about its inventory ofwidget objects. The cell phone can then execute desired objects locally,by copying byte codes.

In this and other implementations, it should be understood that thewidget software code typically executes on the television (for displayon the television screen) or on the cell phone (for display on the cellphone screen), but need not. Instead, the software may execute remotely.For example, a processor “in the cloud” may execute the widgetfunctionality, and simply use the local device for input/output.Similarly, when a user invokes a widget on a cell phone, the system maybe arranged so that the actual program execution occurs on thetelevision's processor—with the cell phone interface simply being usedfor input/output.

As noted, applicant believes that the television should automaticallyadvise the user of widgets relevant to programming currently beingpresented.

There are many ways this can be implemented. One is for the televisionto consult a remote registry each time the programming changes. ASamsung television may consult a Samsung registry maintained on server13 a; a Sony television may consult a Sony registry, etc. IP addressesfor such “home” registries may be hard-coded into the televisionsoftware.

When, for example, a user changes to a new channel, the television cansend a query to its home registry (e.g., Samsung), inquiring aboutwidgets relevant to channel 104 (or Comedy Central channel) at 8:05 pmpacific time. The Samsung registry can return information about relevantwidgets directly, or can simply provide the IP address of a morespecialized registry appropriate to that query. For example, it mayreturn the IP address for a server operated by Comedy Central 13 b,which provides widgets relevant to its programming. The television canthen query the identified Comedy Central server for widgets relevant tothe current time and place.

The television may cache the IP addresses sent from its home registryfor relevant servers, so it need not ping the home registry asfrequently. The TV can thus compile its own DNS of relevant servers, andping the home registry only when its internal DNS does not have theneeded data (or periodically, just to assure freshness of the cachedinformation).

Such process can occur more frequently than just at channel-changes. Atthe beginning of each new program slot (e.g., every 30 minutes), thetelevision may inquire about relevant widgets for that channel and time.

Given network traffic burdens associated with large numbers oftelevisions making such synchronized requests to a limited number ofservers, the widget information may be requested earlier, and cached inthe television—or at an intermediate network node. Or schedules ofrelevant widgets for each channel can be pushed to the television—justas is presently done with electronic program guide data (e.g., a week ortwo of data may be uploaded to the television during off-peak hours).For example, a TV Guide server 13 c that provides electronic programguide information to the television can also provide a listing ofwidgets associated with each program.

(While FIG. 1 shows a few different servers, a great many more can beutilized. Each widget publisher can have its own server, or severalwidgets can be served from a common host, such as Yahoo!)

Still other schedules for updating widget availability can be employed.Each time a football broadcast returns from a commercial break, thenetwork may want to update the roster of available widgets displayed onthe television screen, or remind the user of widgets earlier-presentedthat are still relevant. For example, when returning to an NBC footballgame from a commercial break, the user may be presented with threewidgets: an NBC-branded football schedule widget; an NBC-brandedfootball statistics widget, and an NBC-branded football score widget. Asnoted, each has a “look” that is similar to the look of the NBC footballprogramming with which it is associated—providing a consistency ofexperience. (“Feel” elements may also be shared, such as transitions,sound effects, etc.)

Even commercials may have their own widgets—with Ford's commercial beingaccompanied by a widget that provides a driving simulator for a promotedvehicle, with Disney's commercial accompanied by a widget that providesan extended preview for a promoted movie, etc.

In some embodiments, available widgets are presented within anelectronic program guide UI. A viewer navigating an EPG may be alertedto the presence of associated widgets by a logo or other visual feature.Selecting the logo, or operating a button on a remote control while aprogram is highlighted, brings up a listing of associated widgets on thedisplay screen being used (typically on the television, butalternatively on the cell phone). These widgets can be invoked directlyfrom within the EPG UI. Widgets that are not already resident on thedevice from which they are selected can be downloaded—from anotherdevice in the home network (e.g., from a television to a cell phone) orfrom a remote server 13.

Widgets identified as relevant can be downloaded to the television intheir entirety, or simple icons promoting such widgets can betransferred—with the software itself being transferred if/when thewidget is invoked, or transferred to the cell phone, by the user. (Inthe latter case, the software code may bypass the television, and betransferred to the cell phone directly from a remote server. In suchcase, the television may nonetheless advertise the availability of thewidget(s) using Bonjour.)

In some implementations, a search may be conducted for relevant widgets,using keywords. Such a search can be automatically undertaken by thetelevision upon a prompting event (e.g., a channel change or commercialbreak), or a search can be manually invoked by a user (e.g., who maywant to choose from a broader selection of widgets than are explicitlyassociated with different items of programming by associated servers).The results of the former search can populate a dock along the edge ofthe television screen—as with other widgets. The results of the lattersearch may bypass presentation on the television, and be presentedexclusively on the cell phone.

Over time, the user may transfer a large number of TV widgets onto thecell phone. Selecting among them becomes more difficult as the numbergrows larger.

In some embodiments, the periodic Bonjour broadcasts from the televisionspecify the channel and/or network to which it is currently tuned,and/or the programming that is currently being presented. The user'scell phone receives this information, and adapts its display of TVwidgets accordingly. If the television is tuned to ESPN, the cell phonewill not display stored widgets associated with Disney or CBS news (atleast not on the default screen). Instead, it presents a screen thatincludes only the TV widgets relevant to the identified ESPN program. Asthe user changes channels of the TV, the widgets displayed on the cellphone change correspondingly.

As noted, the widgets themselves are short software applications thatcan be authored using Javascript®, XML, HTML, Adobe Flash, etc. They maybe regarded as mobile agents—software components that can move betweendevices and execution environments. Widget execution can employ aJavaScript runtime environment combined with an XML interpreter. Thisenvironment includes the ability to make calls to the internet toretrieve web pages, to interact with online scripts, as well as fileinput/output. A built-in interface allows execution of OS-specific code,such as shell scripts and COM applications on Windows, and AppleScripton Apple machines.

Although described above as executing on the cell phone while the useris also watching a television screen, the widgets can be executed at anytime or place. The television thus becomes a distribution point forwidgets, but not an anchor for their use.

While a network connection for the television is necessary in certainembodiments, features of the present technology can be employed evenwith older-style televisions, with no computer or network capability. Insuch cases, a cell phone can discern availability of widgets based onvisual or audio signals sensed from the television.

Many television programs are identified by distinctive logos, splashscreens, or musical themes. Within individual programs, certain graphicsmay recur to present different events or information. An example is thescore box presented in basketball games. The ESPN box has a well definedformat (aspect ratio, border width, color, layout, brand artwork, screenplacement, etc.). The NBC Sports box also conveys score information, butis visually distinct from the ESPN box—with its own distinctive format.

These visual features can be captured from the television screen by acell phone camera, recognized, and used to identify associated widgetsthat can be downloaded to the cell phone.

Research into pattern recognition is extensive, and much of it isapplicable in the present context. On large body of work is known as“fingerprinting” and seeks to identify visual objects by distilling aframe of image pixels (or sequence of frames) down into one or more hashcodes or feature vectors by which objects within the frame can berecognized. The reader is referred to two exemplary papers foradditional information: Swaminathan, et al, “Image Hashing Resilient toGeometric and Filtering Operations,” 2004 IEEE Workshop on MultimediaSignal Processing, pp. 355-358, and Kim et al, “Spatiotemporal SequenceMatching for Efficient Video Copy Protection,” IEEE Trans. on Circuitsand Systems for Video Technology, Vol. 15, No. 1, January, 2005, pp.127-132.

Image and video fingerprinting techniques are detailed in patentpublications U.S. Pat. No. 7,020,304 (Digimarc), U.S. Pat. No. 7,486,827(Seiko-Epson), 20070253594 (Vobile), 20080317278 (Thomson), and20020044659 (NEC).

Related to fingerprinting are scale invariant feature transforms (SIFT),as detailed in Lowe, “Distinctive Image Features from Scale-InvariantKeypoints,” International Journal of Computer Vision, 60, 2 (2004), pp.91-110; Lowe, “Object Recognition from Local Scale-Invariant Features,”International Conference on Computer Vision, Corfu, Greece (September1999), pp. 1150-1157, and in U.S. Pat. No. 6,711,293. Again, SIFT dataderived from imagery can be stored in a database, and used asidentification data by which a video program (or portion) can berecognized.

When a cell phone captures an image, features within the image can beextracted by the cell phone processor (or the image data can be referredto a remote processor for analysis, or the process can be distributedbetween the cell phone and a remote processor). Once a set ofcharacterizing features has been discerned, they can be applied to adatabase of reference features—associated with known logos, events,information, or programs. If features discerned from the televisionscreen match a set of reference features from the database,corresponding identification information can be retrieved from thedatabase (e.g., there is an ESPN basketball box score in the capturedimage data).

Once such an identification has been made, one or more correspondingwidgets can be identified. A keyword search can be conducted. Or thedatabase containing the reference fingerprints may also contain links toone or more widgets appropriate for each identified feature.

In the example cited, the widget may be an ESPN basketball applet thatgives the user the ability to browse scores of basketball games, viewhighlights from the in-process game, review statistics for thein-process game or the participating teams, etc.

Audio fingerprinting can be used to similar effect—identifyingdistinctive sound effects, theme songs, etc., that are associated withdifferent programs, from which corresponding widgets can be determined.

Examples of audio fingerprinting are detailed in patent publications20070250716, 20070174059 and 20080300011 (Digimarc), 20080276265,20070274537 and 20050232411 (Nielsen), 20070124756 (Google), U.S. Pat.No. 7,516,074 (Auditude), and U.S. Pat. Nos. 6,990,453 and 7,359,889(both Shazam). Examples of image/video fingerprinting are detailed inpatent publications U.S. Pat. No. 7,020,304 (Digimarc), U.S. Pat. No.7,486,827 (Seiko-Epson), 20070253594 (Vobile), 20080317278 (Thomson),and 20020044659 (NEC).

Another identification technology is digital watermarking (described,e.g., in Digimarc U.S. Pat. Nos. 6,122,403 and 6,590,996 and NielsenU.S. Pat. No. 6,968,564). The audio of most US broadcast television isdigitally watermarked, encoding source and time data, to assist Nielsenin identifying programs for rating surveys, etc. Nielsen maintains adatabase that correlates the source/time data with program names andother identifiers. A cell phone can capture the television audio, andthe encoded watermark can be extracted. The resulting information can beapplied to the Nielsen database. With program identification returnedfrom the database, relevant widgets can be identified. (Or, as above,the database can explicitly associate one or more widgets with differentprograms.)

Other Beneficiaries

By involving a personal second screen, the present technology extendsand enhances the user's enjoyment of entertainment content—withoutimpairing the experience of others who may be watching the same maintelevision screen.

Additionally, the second screen provides benefits to other parties, suchas content-providers, advertisers and audience measurement companies.

Content-providers benefit because widgets on cell phones can extendtheir media footprint from a stationary big screen to a pocket-sized,ever-present appliance. No longer need CBS News be just an evening newsfixture in the den. CBS can jump from the big screen to the smallscreen, and become a user's preferred source of news whenever andwherever. While originally spawned from the big screen, the CBS widgetis not tethered to it. Never before have traditional media companiesbeen given such an easy way to extend their programming reach topersonal devices.

In audience measurement, one shortcoming of existing techniques isuncertainty about who is watching a television screen, and to whatdegree. Personal People Meter devices and the like help identify who isin the room with a television, but provide no insight to the amount ofattention being paid to a screen.

By extending the user experience to a personal second screen, bettermetrics can be obtained about audience involvement, since much of the“second screen” experience is interactive—with users navigating,selecting links, engaging the UI to play games, etc. In some embodimentsof the present technology, user interaction with widgets is reflected indata received by the widget publisher or another data collection entity,allowing the user's engagement with the widget to be quantized. When, ascontemplated by the present technology, widgets proliferate to the pointthat each television program (or even each commercial) has one or moreassociated widgets with it, then tracking widget activity becomes aproxy for viewer engagement with the associated television content, orthe advertising subject. Rich, moment-by-moment information about userinvolvement can then be provided (subject to appropriate privacyprotections, such as anonymization).

As user attention shifts from the big, shared screen to the second, morepersonal screen, the value of the second screen to advertisersincreases. The demographic profile of a particular cell phone user canbe defined much more precisely than the profile for a television, whichis often shared by all members of a household. With more precisedemographics, ads may be better targeted; so that teens' time isn'twasted with diaper commercials, nor senior citizens' time withpromotions for rapper videos. Widgets can include code thatautomatically inserts product placements or other commercial promotionstailored to the owner of the second screen. User responses (e.g.,interactions) can be measured, to help advertisers gauge effectivenessof different promotions. Revenues paid for such precisely engineered adsincrease, helping producers fund content of interest to their audiences.Likewise, better information about programming that engages a particularviewer can help content providers better serve the viewer, e.g., byproducing programming better tailored to the viewer's interests,alerting to the viewer to upcoming programming of likely interest, etc.

CONCLUSION

Having described and illustrated the principles of the technology byreference to a variety of embodiments, it will be apparent that thetechnology can be implemented in many other forms and fashions. Thearrangements particularly detailed are illustrative, not exhaustive.

For example, while reference has been made to cell phones as secondscreen devices, it will be recognized that this technology finds utilitywith all manner of devices—both portable and fixed. PDAs, organizers,portable music players, desktop computers, laptop computers, tabletcomputers, netbooks, ultraportables, wearable computers, servers, etc.,can all make use of the principles detailed herein. Particularlycontemplated cell phones include the Apple iPhone, and cell phonesfollowing Google's Android specification (e.g., the T-Mobile G1 phone,the Motorola Droid phone, and the Google Nexus phone). The term “cellphone” should be construed to encompass all such devices, even thosethat are not strictly-speaking cellular (e.g., WiFi may be usedexclusively), nor telephones.

Similarly, while the specification has made repeated reference toelements such as cell phones and graphical user interfaces, it will berecognized that many of the detailed elements will be superseded inyears to come. Headworn display devices with integrated cameras, andgestural interfaces, for example, are already appearing. Thus, it shouldbe recognized that the detailed arrangements are illustrative, and notmeant to limit the forms in which the detailed technology can bepracticed.

Occasional reference was made to the television remote control. Theremote control typically has a button pad for input, and a transmitter(commonly including an infrared diode) to send instructions to thetelevision. While the remote control can not serve as a cell phone, acell phone can serve as a remote control—to issue commands to atelevision. Rather than sending commands by infrared, the commands maybe sent across the home network, or by Bluetooth, etc. The LCD displayof the cell phone, together with its considerable computational power,make it a formidable remote control. One particular application isnavigating EPGs. The EPG can be presented on the cell phone display, andthe display can be navigated using the superior UI of the cell phone(e.g., touch screen gestures). When a user selects a program, e.g., bytouching a box on a displayed EPG grid, a corresponding command can besent to the television, e.g., causing it to tune to the selectedchannel, or undertake other desired operations (e.g., record a programin the future; play a program earlier recorded; find a program on theweb, etc).

While the specification has focused on television, it will be recognizedthat the detailed principles are equally applicable to other forms ofentertainment content.

The design of cell phones and other devices referenced in thisdisclosure is familiar to the artisan. In general terms, each includesone or more processors (e.g., of an Intel, AMD or ARM variety), one ormore memories (e.g. RAM), storage (e.g., a disk or flash memory), a userinterface (which may include, e.g., a keypad, a TFT LCD or OLED displayscreen, touch or other gesture sensors, a camera or other opticalsensor, a compass sensor, a 3D magnetometer, a 3-axis accelerometer, amicrophone, etc., together with software instructions for providing agraphical user interface), interconnections between these elements(e.g., buses), and an interface for communicating with other devices(which may be wireless, such as GSM, CDMA, W-CDMA, CDMA2000, TDMA,EV-DO, HSDPA, WiFi, WiMax, mesh networks, Zigbee and other 802.15arrangements, or Bluetooth, and/or wired, such as through an Ethernetlocal area network, a T-1 internet connection, etc).

More generally, the processes and system components detailed in thisspecification may be implemented as instructions for computing devices,including general purpose processor instructions for a variety ofprogrammable processors, including microprocessors, graphics processingunits (GPUs, such as the nVidia Tegra APX 2600), digital signalprocessors (e.g., the Texas Instruments TMS320 series devices), etc.These instructions may be implemented as software, firmware, etc. Theseinstructions can also be implemented in various forms of processorcircuitry, including programmable logic devices, FPGAs (e.g., XilinxVirtex series devices), FPOAs (e.g., PicoChip brand devices), andapplication specific circuits—including digital, analog and mixedanalog/digital circuitry. Execution of the instructions can bedistributed among processors and/or made parallel across processorswithin a device or across a network of devices. Transformation ofcontent signal data may also be distributed among different processorand memory devices.

Software instructions for implementing the detailed functionality can bereadily authored by artisans, from the descriptions provided herein,e.g., written in C, C++, Visual Basic, Java, Python, Tcl, Perl, Scheme,Ruby, etc. Mobile devices according to the present technology caninclude software modules for performing the different functions andacts.

While this disclosure has detailed particular ordering of acts andparticular combinations of elements in the illustrative embodiments, itwill be recognized that other methods may re-order acts (possiblyomitting some and adding others), and other combinations may omit someelements and add others, etc.

Although disclosed as complete systems, sub-combinations of the detailedarrangements are also separately contemplated.

Elements and teachings within the different embodiments disclosed in thepresent specification are also meant to be exchanged and combined.

Reference was made to the internet. In other embodiments, othernetworks—including private networks of computers—can be employed also,or instead.

It will be recognized that the detailed processing of content signals(e.g., image signals, audio signals, etc.) includes the transformationof these signals in various physical forms. Images and video (forms ofelectromagnetic waves traveling through physical space and depictingphysical objects) may be captured from physical objects using cameras orother capture equipment, or generated by a computing device. Similarly,audio pressure waves traveling through a physical medium may be capturedusing an audio transducer (e.g., microphone) and converted to anelectronic signal (digital or analog form). While these signals aretypically processed in electronic and digital form to implement thecomponents and processes described above, they may also be captured,processed, transferred and stored in other physical forms, includingelectronic, optical, magnetic and electromagnetic wave forms. Thecontent signals are transformed in various ways and for various purposesduring processing, producing various data structure representations ofthe signals and related information. In turn, the data structure signalsin memory are transformed for manipulation during searching, sorting,reading, writing and retrieval. The signals are also transformed forcapture, transfer, storage, and output via display or audio transducer(e.g., speakers).

In the interest of conciseness, the myriad variations and combinationsof the described technology are not cataloged in this document.Applicant recognizes and intends that the concepts of this specificationcan be combined, substituted and interchanged—both among and betweenthemselves, as well as with those known from the cited prior art.Moreover, it will be recognized that the detailed technology can beincluded with other technologies—current and upcoming—to advantageouseffect.
